1. **State the problem:** We need to find Camilla's unit rate of speed, which is the distance she drives per hour, using the graph that shows time in hours and distance in miles.
2. **Identify points from the graph:** The points given are approximately (1, 50), (2, 90), (3, 130), and (4, 180).
3. **Formula for unit rate (speed):** Speed = \frac{\text{Distance}}{\text{Time}}.
4. **Calculate the unit rate for each point:**
- At 1 hour: \frac{50}{1} = 50 \text{ miles per hour}
- At 2 hours: \frac{90}{2} = 45 \text{ miles per hour}
- At 3 hours: \frac{130}{3} \approx 43.33 \text{ miles per hour}
- At 4 hours: \frac{180}{4} = 45 \text{ miles per hour}
5. **Interpretation:** The unit rate varies slightly but is roughly around 45 miles per hour.
6. **Final answer:** Camilla drives approximately **45 miles per hour** based on the graph.
